Trustees of Tufts University (Tufts) commenced this action for declaratory relief against the defendant insurers, Commercial Union Insurance Company (Commercial Union) and St. Paul Fire & Marine Insurance Company (St. Paul), seeking a declaration that the insurers were under a duty to defend Tufts in a liability claim. The insurers moved for summary judgment. A judge in the Superior Court granted the insurers’ motion, and Tufts appealed. We granted the Tufts’ application for direct appellate review.
The following facts are not in dispute. Tufts purchased liability insurance coverage from both insurers. The policy periods on the Commercial Union policy extended from July 1, 1968, to November 7, 1972. The policy periods on the St. Paul policy covered November 7, 1972, through July 1, 1975.
In June, 1977, the Jacksonville Electric Authority (Jacksonville) acquired by condemnation land in Florida that had once been owned by a subsidiary of Tufts. In April, 1989, Jacksonville filed suit in the United States District Court for the Middle District of Florida against Tufts and two other *846 defendants, to recover cleanup and response costs for environmental damage to the land under the Comprehensive Environmental Response, Compensation and Liability Act of 1980 (CERCLA), as amended, 42 U.S.C. §§ 9601 et seq. (1988). The complaint alleged that: (1) the Eppinger and Russell Company (E & R), The Bernuth Corporation, and Tufts owned or operated a creosote wood preservation facility on the subject parcel until the early 1960’s; (2) E & R was a wholly owned subsidiary of Tufts from 1925 until 1942; (3) while E & R, Bernuth and Tufts owned or operated the facility, arsenic creosote, carbazole, and phenanthrene were released during transfer, storage, and preservation treatment operations on the parcel; (4) Jacksonville had incurred and will incur costs for remedial actions necessary to treat and cap the hazardous substances released on the site; (5) the actions taken are in response to directives from the Florida Department of Environmental Regulation pursuant to a consent order, a copy of which was attached to the complaint. The consent order stated that tests indicated contamination of soil and ground water, and that Jacksonville was attempting to eliminate discharges into the St. Johns River. 2
Tufts moved for summary judgment on Jacksonville’s complaint and a United States District Court judge granted the motion on the basis that Tufts was not an “owner and/or operator” of the site under CERCLA. Jacksonville Elec. Auth. v. Eppinger & Russell Co., 776 F. Supp. 1542 (M.D. Fla. 1991), and Jacksonville appealed. That appeal is currently pending in the United States Court of Appeals for the Eleventh Circuit.
In May, 1989, Tufts demanded that the insurers defend and indemnify it in connection with the Jacksonville action. When the insurers refused, Tufts filed this action in Superior Court in Middlesex County seeking a declaration of its rights under the policies. The Superior Court judge ruled: “The in *847 surers have no duty to defend in this case because the claimant Jacksonville did not become the owner of the property until June, 1977, and thus could not possibly have sustained property damage in relation to this property until two years after the end of the latest policy period.” We reverse.
1. A liability insurer has the duty to defend third-party actions against an insured if the allegations in the third-party complaint are reasonably susceptible of an interpretation that they state or adumbrate a claim covered by the policy terms.

Liberty Mut. Ins. Co.
v.
SCA Servs., Inc.,
Reading these policy provisions together, we conclude that the allegations in the Jacksonville complaint state a claim covered by the policy terms. In the United States District Court complaint, Jacksonville requests reimbursement for the cost of cleaning up contamination on the site caused by release of hazardous substances during the time Tufts owned or operated the site. The “occurrence” is the “injurious exposure” to the hazardous material during the policy periods. The “property damage” is the continued contamination of soil and groundwater on the site during the policy periods caused by the release of the hazardous material.
Hazen Paper Co.
v.
United States Fidelity and Guar. Co.,
The insurers argue that the proper inquiry under these policies is.not whether property damage occurred during the policy period, but whether the entity making the claim sustained harm during the policy period.
Hoppy’s Oil Serv., Inc.
v.
Insurance Co. of N. Am.,
In construing this policy, it is also appropriate “to consider what an objectively reasonable insured, reading the relevant policy language, would expect to be covered.”
Id.
We conclude that a reasonable policyholder, reading this policy language, would expect coverage in these circumstances. There is no restriction in the language of the policy requiring that the claimant possess an ownership interest in the property at the time the damage occurred. “We read the policy as written. We are not free to revise it or change the order of the words.”

Gilbane Bldg. Co.,
The judge and the insurers rely on

v.
Insurance Co. of N. Am.,
Gilbane, supra, was a declaratory judgment action brought by the insurer of two construction firms alleged to be responsible to the John Hancock Mutual Life Insurance Company for faulty design of the John Hancock Tower that led to the failure of glass window panels and resulting property damage. Id. at 144-146. The insurer contended that a “[c]are, custody, or control exclusion” in the comprehensive general liability policy issued to the construction companies justified its disclaimer of coverage. Under that exclusion, there was no coverage for property “being installed, erected or worked upon” by the companies (emphasis in original). Id. at 151. The insurer argued that the failure of the window panels constituted a single occurrence that commenced when the companies were still working on them, and therefore that the damage was not within the policy. Id. The court rejected the argument, stating: “The time of the occurrence of an accident within the meaning of an indemnity policy is not the time the wrongful act was committed, but the time when the complaining party was actually damaged.” Id. at 152.
It is in this context that the rule followed in
Gilbane, supra,
must be read. The underlying claimant in
Gilbane, supra,
owned the damaged property at all relevant times. The court, therefore, could refer to damage to the “complaining party” instead of damage to the “property.”

v.
Glens Falls Indem. Co.,
“In the midst of this rush to adopt the ‘general rule’ of Remmer, it must be remembered that the rule is just that: a general rule. It is not universal; it is not without exception. . . . [Here, the insured] is now being sued for property damage (physical injury to tangible property) which may have commenced during one of the last two . . . policy periods — precisely what the policies say they cover. Use of the Remmer rule to impose a prerequisite to coverage not expressed in the policies (i.e., that the eventual claimant had to own the damaged property *852 during the policy period) would be contrary to every fundamental rule of insurance policy construction.” (Citation omitted.)
Garriott Crop Dusting Co., supra at 794-795.
There are additional reasons that support our interpretation. If Tufts were sued under CERCLA or G. L. c. 21E for allegedly contaminating two separate properties — one owned by the same party throughout the period during which the property damage occurred, and the other recently sold to a new owner — under the insurer’s interpretation coverage would exist for the former claim but not the latter. See
Gar-riott Crop Dusting Co., supra
at 795 (“We do not see any reason why the existence of coverage
vel non
should turn on fortuitous events or conditions wholly outside the insured’s control”). Moreover, since CERCLA and the Massachusetts equivalent, G. L. c. 2IE, attempt to place the ultimate responsibility for cleaning up hazardous waste on those entities responsible for the contamination, see 42 U.S.C. § 9607; G. L. c. 2IE, § 5
(a),
we think it entirely logical that the insurer whose policies are in effect during the time that the property damage is alleged to have occurred be required to defend the insured. See
Jacksonville Elec. Auth.
v.
Eppinger & Russell Co.,
2. The “owned property exclusion” in each policy, which prevents an insured from obtaining coverage for damage or injury to “property owned or occupied by or rented to the insured,” does not preclude our result. The facts alleged in the complaint and those facts known by the insurers do not establish that Tufts owned the contaminated property.

3. Commercial Union also argues it had no duty to defend Tufts because the property damage to the Jacksonville site did not manifest itself until after its last policy period. Commercial Union, however, again ignores the language of the policy itself. The policy requires a duty to defend where there is an “occurrence,” including injurious exposure to conditions, that results, during the policy period in “property damage,” a term defined as injury to, or destruction of, property. Nothing in the language of the policies requires that the claimed property damage be discovered or manifested during the policy period. The inquiry instead, is whether the property damage, as defined in the policies, “occurred” within the policy period and within the meaning of the word “occurrence.”

We have already said: “The contamination of soil and groundwater by the release of hazardous material involves property damage.”

In deciding this appeal we need not reach the question whether another trigger is appropriate; we need only decide that the manifestation trigger is inappropriate.

We note that different triggers may be applied to different types of injuries and property damage.

See, e.g.,
Trizec Properties, Inc.
v.
Biltmore Constr. Co.,
4. Commercial Union argues that its policies are not triggered because the property damage at the site was a loss in progress at the inception of its policy periods. Their argument, however, raises questions of fact as to when property damage at the site occurred and, therefore, cannot be a basis for sustaining summary judgment.
5. Commercial Union also contends it has no duty to defend because E & R’s operations were not scheduled hazards in its policies. The policy which purports to be com *856 prehensive general liability insurance provides that “coverages” includes “property damage liability” and that a specific premium was charged for the coverage. Item 3 of the declarations page states: “The insurance afforded is only with respect to such of the following coverages as are indicated by specific premium charge or charges.” Nowhere does the policy unambiguously provide that coverage is limited to the specific hazards listed in the schedule. Thus, the very reading of the policy now urged by Commercial Union could not properly be the basis of summary judgment in its favor.
A related issue is Commercial Union’s argument that it has no duty to defend because Tufts’ failure to identify E & R as a scheduled hazard increased Commercial Union’s risk of loss. The policy does not seek to identify the ownership of stock or clearly require the insured to disclose property it may have controlled in the past as the result of its ownership of corporate stock. Commercial Union argues that at the very least these issues should be resolved by further proceedings in the Superior Court. We agree.
6. Finally, we decline to accept Commercial Union’s assertion that we should reject Tufts’ arguments as not based on the record before the Superior Court. Our decision is not based on Tufts’ characterization of the policies as “standard form” and “classic contracts of adhesion.”
Judgment reversed.
Notes
The complaint does not specify the precise dates of release, contamination, or migration of the pollutants but can be reasonably read as alleging such damage throughout the time periods encompassed by the complaint.
“Otherwise stated, the process is one of envisaging what kinds of losses may be proved as lying within the range of the allegations of the complaint, and then seeing whether any such loss fits the expectation of protective insurance reasonably generated by the terms of the policy.”
Continental Casualty Co.
v.
Gilbane Bldg. Co.,
The policy language quoted is taken from Commercial Union’s comprehensive general liability policies. St. Paul’s policies are denominated as “ [c] omprehensive [h]ospital [1] lability” policies. However, the St. Paul policies contain property damage liability endorsements that require the insurer to “pay on behalf of the Insured all sums which the Insured shall become legally obligated to pay as damages because of injury to or destruction of property, including the loss of use thereof, caused by [occurrence] .” We reject St. Paul’s argument that this language does not provide comprehensive general liability coverage.
While the language quoted is taken from both policies, the St. Paul policy also requires that the damage occur “during the policy period.”
The court in
Garriott Crop Dusting Co.
v.
Superior Court of Kerns County,
That court also concluded that “no genuine issue of material fact exists which would justify piercing the corporate veil to hold Tufts liable as an owner under CERCLA.”
Jacksonville Elec. Auth.
v.
Eppinger & Russell Co.,
Only a few courts have adopted the “manifestation trigger” urged by Commercial Union. Those that did adopt the trigger reasoned that the bodily injury or property damage at issue does not occur until manifested. K.S. Abraham, Environmental Liability Insurance Law 97 (1991). See
Eagle-Picher Indus., Inc.
v.
Liberty Mut. Ins. Co.,
Apart from the “manifestation trigger,” the three most common “trigger theories” include: the exposure trigger (policies in effect during years claimant’s property tortiously exposed to hazardous material triggered), the continuous (or multiple) trigger (property damage occurs during each year from the time of first hazardous exposure through manifestation), and the injury-in-fact (or actual injury) trigger (requires inquiry into when property damage actually occurred). S.M. Popik, Introduction to the CGL Policy Form: Occurrence Versus Claims-Made Policy Forms in Comprehensive General Liability Policies (P.L.I. Commercial Law & Proc. Course Handbook No. A-658 1993). K.S. Abraham, Environmental Liability Insurance Law 96-98 (1991).
We note that we are concerned here only with the insurers’ duty to provide or pay for a defense to the insured, and not with their duty to indemnify for damages from a final judgment. “[A]n insurance company’s duty to defend is broader than its duty to indemnify. An insurer must indemnify its insured when a judgment within its policy coverage is rendered against the insured. The duty to defend, however, is antecedent to, and independent of, the duty to indemnify.”
Boston Symphony Orchestra, Inc.
v.
Commercial Union Ins. Co.,
Indeed, one commentator has noted that, given variations in the injury processes associated with different kinds of environmental harms, different triggers for environmental harms may be appropriate. K.S. Abraham, Environmental Liability Insurance Law 105 (1991).
